摘要： Phosphor particles coated with a mixture of GeO2 and SiO2 or a mixture of WO3 and SiO2 are dispersed in an aqueous solution of a photosensitive resin together with a protective dispersing agent for the particles in the solution to form a slurry. Y2O3 :Eu phosphor particles with the coating are chemically stable and do not hydrolize in the slurry. The slurry is then applied to the inner surface of a glass tube. The resulting phosphor film is dried, printed and developed by the photographic technique to form a desired pattern of the phosphor material. By the invention manufacturing a bright color picture tube employing Y2O3:Eu phosphor becomes possible in commercial success.
